This is an excellent, concise analysis of the events at the Daiichi 1 reactor at Fukushima following the recent earthquake and tsunami, and why we need not be afraid of nuclear power generation.
This is a similarly excellent overview of the situation in Japan right now from an english-speaking foreigner living and working there.
I recommend that everyone read both of them; it will give you a much better idea of the situation than anything coming from the hysterical news media.
